摘要	The settlement of surrounding soils will be caused by dewatering engineering of foundation pit in phreatic aquifer, which easily leads to a series of accidents. in order to solve the problem, The effect of the group wells was ignored. The equation of the water-table depression was solved on the supposition of Dupuit presupposition. The effective stress principle of unsaturated soil in draining areas was leaded and the horizontal component of the additional stress due to seepage force at the same time was considered. Then the settlement of the soil layers above and under the cone of water-table depression was respectively calculated based on the layer-wise summation method, and the actual settlement around the wells after dewatering was the sum of the both. The comparison and analysis with numerical simulation and monitoring of the engineering examples show that the calculation method has a practical engineering value. © 2016, Zhejiang University Press.
